Intel said today it is investigating an issue with Broadwell and Haswell CPUs after customers reported higher system reboot rates when they installed firmware updates for fixing the Spectre flaw.

The hardware vendor said these systems are both home computers and data center servers.

“We are working quickly with these customers to understand, diagnose and address this reboot issue, “said Navin Shenoy, executive vice president and general manager of the Data Center Group at Intel Corporation.

“If this requires a revised firmware update from Intel, we will distribute that update through the normal channels. We are also working directly with data center customers to discuss the issue,” Shenoy added.

The Intel exec said users shouldn’t feel discouraged by these snags and continue to install updates from OS makers and OEMs.

While Shenoy has not clarified what systems are experiencing higher reboot rates, it could only be Linux systems for which Intel started rolling out CPU microcode updates yesterday. These firmware updates mitigate the Spectre flaw.

AMD faces similar issues with Meltdown & Spectre patches

Earlier today, AMD also announced it will start shipping microcode updates that mitigate the same Spectre flaw.

AMD customers have too faced problems earlier this week when Windows updates meant to mitigate the Meltdown and Spectre flaws caused BSOD errors.

Microsoft paused the rollout of these updates to investigate. AMD said only AMD Opteron, Athlon and AMD Turion X2 Ultra families were affected.
